Koordinationswechsel bei Protonierung: Die Borylmangankomplexe 1 reagieren unter Protonierung zu den kationischen Boran‐σ‐Komplexen 2. Die Zersetzung von 2 verläuft unter heterolytischer Spaltung der Metall‐koordinierten B‐H‐Bindung.

Photolysis of Cp*Fe(CO)2Me in the presence of BH3·PMe3 (1) produced a boryliron complex Cp*Fe(CO)2(BH2·PMe3) (2a). Complex 2a and the ruthenium analogue Cp*Ru(CO)2(BH2·PMe3) (3) were accessible by the salt-elimination reaction between K[Cp*M(CO)2] (M = Fe, Ru) and BH2Cl·PMe3.

Since the discovery of its anomalous resistivity and ferrimagnetism, NaV6O11 received wide interest. Its structure (P63/mmc, Z = 2) consists of hcp layers of O and Na atoms. V(1)O6 octahedra form a Kagome; lattice, while V(2)O6 octahedra form a face-sharing dimer. V(3) cations are five-fold coordinated to oxygen.
